Basic About Computer Firewall

My thought about computer firewall.

A firewall is a computer software to provide protection from hacking attempts on the Internet. It is very important to install a proper firewall software to protect your computer against spyware and virus infections. A large number of security companies have developed software firewall. Some of these programs are free for personal use.

A software firewall is basically a "packet sniff". Data is transmitted via the Internet moves to form packets. Firewall Software intercepts these packets, analyzes its content and decide whether it is harmful to your computer. If the package contains harmful content, the firewall blocks it from accessing your computer, preventing damage to your computer.

Most spyware, malware and virus programs can be prevented by installing a firewall properly. Firewalls can also prevent software from accessing the Internet and send information without the user's knowledge. Even if a virus is installed on your computer, it will still not be able to access the Internet and send sensitive data such as numbers, credit cards, etc.

The latest version of Microsoft Windows, Windows Vista has a firewall built into it. This means that if you're using Vista, do not download and install additional software firewall. But if you still want to install a third-party firewall, you may do so for extra protection.

For maximum protection, it is advisable to invest in an Internet Security Suite. This is a software package that combines a virus scanner, scanner, email protection spyware and firewall. By installing this software, you can get complete protection against all types of malware programs which spread via the Internet.
